Agdam was a city in Southern Azerbaijan. Today the city which bustled with life just 15 years ago is under Nagorno-Karabakh control, completely deserted and in ruins; it is known as the "Hiroshima of Azerbaijan" and is under Armenian control. Officials of Nagorno-Karabakh advise travelers to stay away from the city, due to its close approximaty to Azerbaijan border.
Probably the only way to visit the ghost town is with a taxi. It should cost something between 8000-12000 drams (16-20 eur). It is up to the driver if he takes the risk to take you there. Although he/she says yes it can happen that the military stops you around Agdam and turns you back. Be careful, it is officially not allowed to visit the town for turists as it is still considered as a war zone.
